Problems solved by technology

Machine threaded coupling surfaces between the metal body and the metal coupling nut of U.S. Pat. No. 5,795,188 and similarly configured prior coaxial connectors significantly increase manufacturing costs and installation time requirements.
Another drawback is the requirement for connector disassembly, sliding the back body over the cable end and then performing a precision cable end flaring operation, which retains the cable within the connector body during threading.
Further, crimping and / or compression becomes impractical with larger diameter coaxial cables, as the increased diameter, sidewall thickness and / or required travel of the corresponding connector / back body(s) increases the required force(s) beyond the levels deliverable by conventional crimp / compression hand tools.

Embodiment Construction

The inventor analyzed available solid outer conductor coaxial connectors and recognized the drawbacks of threaded inter-body connection(s), manual flaring installation procedures and crimp / compression coaxial connector designs. Insertion coupling coaxial connectors, for example as disclosed in the inventor's commonly owned U.S. Utility patent application Ser. No. 12 / 264,932, titled “Insertion Coupling Coaxial Connector”, filed Nov. 5, 2008, currently pending and hereby incorporated by reference in its entirety, introduces several significant improvements to the coaxial connector arts, eliminating the need for manual flaring of the outer conductor and / or high torque threading of the coupling nut into the connector body during outer conductor end clamping connector to cable end interconnection. Similarly, several improvements to the insertion coupling coaxial connector are disclosed in the inventors commonly owned U.S. Utility patent application Ser. No. 12 / 611,095, titled “Insertion ...

Abstract

A grip ring for a coaxial connector couples with a coaxial cable with a solid outer conductor. The c-shaped ring is provided with a gap between a first end and a second end. A shield portion extends from the first end and a slot portion dimensioned to receive the shield portion provided in the second end. The shield portion keys with the slot portion as a diameter of the grip ring is reduced. An inner diameter of the grip ring is provided with a grip surface. Further, the grip ring may be provided with a flange edge at the cable end projecting from the outer diameter.

Description

BACKGROUND1. Field of the InventionThis invention relates to electrical cable connectors. More particularly, the invention relates to an internal grip ring for a solid outer conductor insertion coupling type coaxial cable connector.2. Description of Related ArtCoaxial cable connectors are used, for example, in communication systems requiring a high level of precision and reliability.To create a secure mechanical and optimized electrical interconnection between the cable and the connector, it is desirable to have generally uniform, circumferential contact between a leading edge of the coaxial cable outer conductor and the connector body. A flared end of the outer conductor may be clamped against an annular wedge surface of the connector body via a coupling nut. Representative of this technology is commonly owned U.S. Pat. No. 5,795,188 issued Aug. 18, 1998 to Harwath.Machine threaded coupling surfaces between the metal body and the metal coupling nut of U.S. Pat. No. 5,795,188 and si...
